Xiaomi has unveiled the Mijia Purifying Humidifier 3 Pro, a combined air purifier and humidifier aimed at larger apartments and houses. The device is already listed on Youpin, with sales in China starting on July 22 at 1,699 yuan — about $250.
Built to cut down on clutter, the new model combines both functions in a single корпус instead of requiring two separate devices, power cords, and floor spots. Xiaomi says the humidifier can output up to 2,000 ml per hour. According to the company’s internal tests, it can raise humidity in a standard bedroom in about 7 minutes, or in a larger room in 19 minutes.
The unit includes an 8-liter tank, which Xiaomi says can deliver up to 16 hours of operation in sleep mode without refilling. It also uses a one-way water circulation system, so used water does not flow back into the main tank, a design intended to reduce bacteria and cloudy residue. Xiaomi also claims electrolysis-based water sterilization and a washable antibacterial filter.
Air purification is handled by a six-stage filtration system that targets large particles, PM1, PM2.5, formaldehyde, and common allergens. Xiaomi rates the device at 422 m³/h CADR for particulate matter and 247 m³/h CADR for formaldehyde, putting it closer to standalone mid-range and higher-end purifiers than to basic combo units.
Purification and humidification can run independently. If a room’s humidity is already comfortable, the Mijia Purifying Humidifier 3 Pro can be used as a purifier alone.

On top, Xiaomi has added a dome-shaped LCD display with automatic brightness adjustment. It shows temperature, humidity, dust concentration, and PM1 and PM2.5 levels in real time. The device also supports the Mijia app for remote control, status checks, and filter-life monitoring, along with voice commands through XiaoAI.
The hardware is designed for easier day-to-day use: water is poured in from the top, the tank is fully removable and has a handle, and the base includes 360-degree wheels. A DC brushless inverter motor powers the unit, and Xiaomi lists sleep-mode noise at 28.1 dBA.
In China, Xiaomi is pitching the device into a market where hybrid climate-control products compete with standalone models from Philips, Dyson, and local brands. The company’s bet is clear: combine strong specs with a lower price.
